MACHINE EOFR'AUTOMATICALLY JGATHERING AND DELIVERING GLASS;

SPECIFICATION forming part of Letters Patent No. 744,274, dated November1'7, 1903.

Application filed March 14, 1906. Serial No. 8,663. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM FRANCIS AL- TENBAUGH, a citizen of theUnited States, residing at Tiffin, in the county of Seneca and State ofOhio, have invented certain new and useful Improvements in Machines forAutomatically Gathering and Delivering Glass, of which the following isa specification.

The following description read in connection with the drawings willenable any one skilled in the art to which my invention relates tounderstand its nature and to practice it in the form in which I preferto employ it; but it will be understood that my invention is not limitedto the precise form herein illustrated and described, as variousmodifications and equivalent changes may be made and adapted by theskilled constructor to carry out my invention.

Referring to the drawings, Figure 1 represents in side elevation amachine embodying my invention and in which the gathering instrument hasbeen moved forward into the working chamber and its operating mechanismelevated to cause the instrument to be presented at its highestgathering pitch to the surface of the glass for gatheringthe properquantity for a working charge. Fig. 2.represents a like view showing theoperating mechanism of the gathering instrument as having been loweredto complete the gather and bring the instrument to a horizontal positionto be moved out to deliver the charge. Fig. 3 is a top view of so muchof the machine, showing the gathering instrument as having been movedback and swung out to deliver the charge, the carriage,and the means forreciprocating it. Fig. 4 shows a part of the carriage, the leaf-hingepivotedthereto, and the guide-arm, which in its action as the carriagereciprocates causes the gathering instrument to be swung out at the sideand again into aiinement. Fig. 4% is a side View of the hinge shown opento' illustrate both the hinging and the pivoting of the carriage toallow the dipping of the gathering instru ment at the end of itstrackway 26 at the point of delivery, as in Fig. 3. Fig. 5 shows in topview the carriage-actuating clutch engaged as when the carriage ismoving in or out. Fig. 6 is the hand-lever 75, seen in Fig.

3 as pivoted to the rear end of the carriage and having by its shoulder76 automatically disengaged from the carriage-actuating clutch, and inFig. 5 this hand-lever is seen as having been by hand lifted from itsengagement with the clutch-lever 65 to allow the engagement of theclutch. Fig. 7sho'ws in side view the clutch device of the basestructure on which the carriage-track frame is mounted and by which theelevation and lowering of the track-frame is automatically controlled,the arm 104,Fig.14, depending from the trackframe being shown as havingdisengaged the clutch on the descent of said frame. Fig. 8

is a top View of the shifting parts of the same clutch device. Fig. 9shows in'top'view the belt-'cord-operated lever device for automaticallychanging the speed of the gathering instrument by changing the belt-cord85 from the larger pulley 86 to the smaller pulley 92; and Fig. 10 is aside view of the same, the belt-cord being changed to thesmallest pulleywhen the gathering instrument is rising and moving out with the chargeto cause it to quickly take up and. wind 011 the wireglass which isdrawn up with the charge, and

thereby prevent it from being deposited on the bridge of the opening ofthe working chamber. Fig. 11 is a detail of the lever and wedge deviceshown in Fig. 9, by which the levers are actuated for shifting thebeltcord automatically as the track-frame descends tobring the leverdevice 68 in engagement with the wedge 89 for changing the speed of thegathering instrument. The relation of this wedge to the fixed basestructure is seen in Figs. 1, 2, and 15. Fig. 12 shows in transversesection the track-frame 6, the carriage thereon, the clutch-connectingarm 78 on the go track-rail, and the pivoted trip-arm 79 on thecarriage, whereby when the latter having moved to the limit of itsadvance, with the gathering instrument at its highest pitch, as

in Fig. 1, the arm 79, standing horizontally, strikes the vertical arm78 and pushing it forward causes by its connecting-rod 77, Fig.

3, the said arm 78 to pullthe clutch-lever 65,

so as to disengage the clutch 63, and thereby stop the advance of thecarriage while the we gather is being made. The track-frame will thenbegin to descend, and reaching the limit of its descent will bring thetrip-arm 79 in] Sheet 1, shows in top-view so much of the contact withthe fixed stop 80 on the basestructnre, and thereby lift said trip-armand release the clutch-connecting rod 77, as shown by dotted lines insaid figure, and allow the clutch 63 to be engaged by its spring 64 tomove the carriage out as the latter and its supporting hingedtrack-section is brought into alinement with the main-track frame, asshown in Fig. 2. Fig. 13 isa vertical section of the chuck, showing thegearing by which the gathering instrument is rotated. Fig. 14 shows inelevation the base structure and the relation of its clutch device tothe elevating and lowering frame which supports the trackframe, the viewbeing taken from the rear side, the track-frame in its lowest positionand the clutch disengaged to arrest the elevating movement while thecarriage is moving back to swing out the instrument to deliver thecharge, as in Fig. 3. Fig. 15 shows the driving-gear side of themachine, the track-supporting frame being partly elevated by the crankconnections and with it the track and operating connectionsof thegathering instrument. Fig. 16 is a top view showing the gearing of thebase structure, the track-frame line-shaft 37, and its connection withthe base-center shaft 33, which is operated by the base-gearing tooperate the lineshaft, and also the relation of the base-stop 80 to thetrack-frame. Fig. 17 is a side view showing a portion of the carriage,the pivoted arm 79 thereon, the track-frame, the pivoted arm 78 thereonand the relation of these pivoted arms to the fixed base-stop 80 on thebase structure at the time the carriage has moved forward and broughtitshorizontal pivoted arm 79 against the vertical arm 78 of the track-frameand moved said arm to disengage the clntch 63 by the connecting-rod 77.In this view the track-frame is in the position on its descent and justbefore the pivoted carriage-arm 79 is caused to strike upon the fixedstop 80 and be thereby lifted to disengage it from the track-frame arm78 to release the clutch-connecting lever to allow the engagement of theclutch to effect the backward movement of the carriage with the gatheredcharge. Fig. 18 is a top view of the same, the pivoted arm 79 havingengaged the vertical arm 76 and moved it back, disengaging the clutch byits connecting-rod 77. Fig. 19 shows a side view of the pivoted arm seenin Figs. 17 and 18 in its relation to the fixed stop 80,at the momentthe track-frame is at the limit of its descent, the carriagearm 79disengaged by said stop to allow the clutch 63 to be engaged, and thegathering instrument thereby to be withdrawn in a horizontal position,as in Fig. 2. In this view the movable fulcrum is shown at the limit ofits function in controlling the gathering instrument and in whichfunction it has caused the gathering instrument to elfect an advance ofabout two inches and a half. Fig. 20,

track-frame, the carriage, the gathering instrument, and the swingingguide-arm 71 as illustrates the function of a bracket-fender 123, Fig.20, in the track-frame, with which the carriage-guide arm engages toprevent the carriage from being turned laterally on its pivot 23, Figs.4 4, which it tends to do by the pulling of the sticky glass in beingwound upon the iron; and Fig. 21 illustrates the movement of thegathering end of the instrument as controlled by the movable fulcrum,which controls such movement simultaneously with the elevation andlowering of the driven end of such instrument. Fig. 22 shows in top viewthe slack-take-np-pulley device of the belt-cord for rotating thegathering instrument.

My improved machine may be employed either in gathering glass for themanufacture of pressed glassware or of blown glassware. In the formercase the glass having been gathered upon the gathering-tool or punty ismoved into a convenient place, preferably in close proximity to themold, where it can be cut off without removing the punty from themachine. In the other case the blowpipe on which the glass is gatheredis preferably arranged so that it is readily removable from the machineand so that after its removal another blowpipe may be substituted forit. In the drawings I show the machine provided with a punty, which neednot be removed in order to carry out the purposes of the machine. Wherethe machine is to be used for gathering glass on a blowpipe,I may usethe mechanism described in my prior patent, No. 618,975, dated February'7, 1899.

In Figs. 1 and 2 is seen the Working chamber of tank 1, in which themolten glass is maintained, preferably, at a uniform level, and theworking opening 2 therein for the entrance of the gathering instrument.The relation of the machine to this opening is such that the gatheringinstrument may enter the molten glass at a high pitch and may leave theopening more nearly horizontally, and the opening will give a clear wayfor this purpose.

The gathering instrument 3 is mounted upon a pivoted swing-frame 4.,hinged upon a carriage 5, which is movable upon the rail 6 of atrack-frame to carry the gathering instrument into and from the workingchamber. The track-frame is mounted upon an elevating and lowering frame7 30, mounted in a suitable base structure.

The gathering instrument is set in a rotary holder or chuck-shaft 8,Fig. 13, revoluble in a bearing-block 9 on the swing-frame plate 4, andin order to support the gathering instrument and hold it in properposition I employ a holder consisting, preferably, of a pair of rolls10, upon which the gathering instrument rests and against which ashoulder 11 thereon may hear. The receiving end of the chuck extendsoutside of its bearing-block and may be provided with screws 12 forholding the instrument. I

A portion 13 of the swing-frame 4 carries suitable driving-gearing bywhich the chuck is rotated, which may comprise a pinion 14 von the outerend of the chuck-shaft engaging a like pinion 15 on a short shaft 16above the chuckshaft. This short shaft projecting from the bearing-blockhas a bevel-gear 17, which engages a bevel-pinion 18 on a vertical shaft19, mounted in the end of the swingframe 4 and driven'in a way which Iwill presently state. This frame 4 is pivoted to the carriage 5, and inorder that the carriage may be moved easily upon its track 6 I prefer toprovide it with wheels 21, Figs. 1, 2, and 12, mounted on hangers 20 andadapted to run upon the upper and under sides of the rail 6. To pivotthe swing-frame to the carriage and to make it capable of a doublepivotal motionnamely, a horizontal swingfor the purpose of permittingthe gathering instrument to move laterally to the delivering positionafter glass has been gathered thereon and also to dip at the end of itsswing in order to bring the glass to the mold or mar.vering-block,'1prefer to use a leafhinge 22, Figs. 4, 4, the pivot-bolt 23 passingthrough the lower leaf and being secured by a nut, while the upper leaf24 is secured to the lower leaf by a pintle 24 and is fixed to theswing-frame. The swing-frame swings laterally on the axis of the pivot23 and dips vertically on the axis of the pintle 24. The frame 4 has awheel 25, mounted upon a way 26, which projects laterally from thecarriage and is provided with a depressed portion 74, which will causethe frame to dip when the wheel reaches it in the course of its sideswing, as shown in Figs. 3, 4.

A convenient length for the track-frame is about twelve feet, and it maybe formed of longitudinal rails or plates 6, suitably braced and adaptedto carry the operating parts of the carriage and gathering instrument.It is formed with a portion 27 of its length ar ranged to dip or movevertically, and for this purpose said dipping portion is preferablyhinged, as shown in Figs. 1 and 2. It is on this hinged part that thecarriage is run and is caused to dip, so as to present the gatheringinstrument to the glass at a high gathering pitch or angle by meanswhich I shall presently state.

The track-frame 28 is mounted upon the standard 7 by a bracket 29, Figs.3, 15, 16, so that preferably a greater portion of its length standsforward thereof, and in order to raise and lower said standard I mayemploy any suitable lifting mechanism, preferably the following: Across-head 30 is fixed to the standard and fitted at each end to a slideupon fixed standards 31 31, which are connected at their upper ends by ahorizontal cross-head 32, through an opening in which and in a lowercross-head 32 the central I and seated on the bracket 29.

4 chain to travel standard'7'passes and is: guided and braced. A shaft33, whose function isto drive the endless chain or other driving gear bywhich the carriage is reciprocated on the trackframe, is mounted in astep 34 and preferably passes through the standard, which is hollow forthis purpose, and through a bevelpinion 35, which is splined upon saidshaft This bevelpinion 35 engages a bevel-pinion 36 on a horizontalshaft 37, mounted on bearings 38011 the track-frame, and it is therotation of this vertical shaft 33 which causes the reciprocation of thecarriage through the splined pinion 35, as I will now state. For liftingand lowering the track -'frame a shaft 38' is mounted'on fixed bearingsand has cranks 39, connected to links 40, depending from the cross-head3O ofthe lifting-frame, so that the rotation of said shaft 38 by itscrank and link connections elevates and lowers the track-frame to theextent of the throw of the cranks.

For rotating the crank-shaft 38 a second shaft 41 is mounted in theupper ends of brackets 42, rising from the bearings of the crank-shaft38 at the rear side of the standards, and has a gear-wheel 43 on itsouter end and a pinion a, Figs. 14, 15, 16, which engages a gear I) onsaid crank-shaft. For rotating this second shaft 41 a short power-shaft45, Figs. 15, 16, mounted in studs 46, has on its outer end a pulley 47,driven by a powerbelt, while a pinion 48 on said shaft engages the gear43 on the shaft 41. On this shaft 41 is a bevel-pinion 44, which engagesa bevel-pinion 49 on a vertical shaft 50, mounted ina' step 51 and in abracket 52 on one of the fixed standards. A gear 53 on the lower end ofthis vertical shaft engages a pinion 54 on the lower end of the verticalshaft 33 of the hollow standard, so that from the powershaft 45the'track-frame is elevated and lowered by the cranks and the carriagereciprocated by the central shaft.

The carriage-driving shaft 33 has a top bevel-pinion 35, which, by abevel pinion 55,

Figs. 3 and 5, on the outer end of the lineshaft 37, drives abevel-pinion 56 on a short transverse shaft, which is supported in achain at its other endby a pin 61, so that the rotation of the shaft 33causes the rotation of the side clutch-connected shaft 37, which,driving the sprocket-wheel 57, causes the and the carriage to bereciprocated. v

The connection of the arm 60 with the carriage is in advance of thepoint 61, at which it is connected to the chain, so that when &

said point reaches the forward end of travel of the chain the arm willproject forwardly. This is a convenient arrangement, because it causesthe carriage to move beyond the end of the chain and does away with thenecessity of extending the chain forward upon the pivoted or dippingsection of the track-frame.

To control the driving of the chain, I may employ clutch mechanism,comprising a hubclutch part 62, Figs. 3 and 16, on the side shaft 37,which is fixed to the bevel-pinion 55, and both are loose on said shaft,which can therefore rotate continuously, while the said hub-clutch partand its chain-connected gear are only actuated when the clutch isengaged. For this purpose the slidable clutch part 63 on said shaft isheld normally engaged by a spring 64 to effect the rotation of the chainand the reciprocation of its connected carriage, while by means of alever 65, pivoted to the frame, the slidable member of the clutch isshifted and held out of gear to stop the carriage at the limit of itsrearward and of its forward movements in a way which I shall presentlystate. This clutch I call the starting and stopping clutch.

The dipping of the hinged track-rail section, with the carriage thereon,is accomplished by providing a supporting or guide fulcrum-bar G6, whichsupports the hinged section while the other section is being movedvertically, and thus causes the hinged section to incline or dip whilethe other section is rising and causes it to come into alinement whenthe other section descends. This bar 66 is secured to the fixed portionof the machine and curves downwardly with its concave side toward theworking tank, and depending from the hinged track-frame section 27, nearthe hinge thereof, is a bracket 67, having pivoted thereto asupporting-arm 68, which has a roller 69 adapted to travel upon thefulcrumbar. This supporting-arm 68 has means by which it can be adjustedso as to control the extent to which the hinged track-section can dip,and for this purpose I may employ a screw 70, arranged to engage thebracket and to vary the angle at which the arm 68 stands relatively tothe hinged section. This adj ustment enables me to adjust the angle orpitch of the gathering instrument at the time when it reaches the end ofits downward motion and makes contact with the molten glass, and byvarying this adjustment I may Vary the extent of the immersion of theend of the instrument, and thus vary the amount of glass gatheredthereon, or may adjust the dipping of the instrument to accommodate itto the level of the glass in the tank. Such adjustment is important,because the end of the gathering instrument should be immersed at auniform depth in the surface of the glass to secure gathers of uniformweight.

The swing-frame 4 carries the chuck-shaft for the gathering instrument,the devices for rotating and speeding it, and the means by which saidframe is swung out at the side of the machine to deliver the gather andswing back to its normal position for gathering a charge. For thispurpose 'I prefer to employ a guide-arm 71, fixed to the under pivotedleaf 22 of the hinge, so that the hinge forms the turn-table and is alsothe hinge on which the rolls will cause the pivoted frame to swing outat the side with the gathering instrument, while the forward movement ofthe carriage causes the pivoted frame to swing back into alinement withthe carriage. The guide-arm stands in a position to enter between theguide-rolls at the proper point as the carriage moves back to swing theframe out and to leave the guide-rolls at the point at which it hasswung said frame back into alinement with the carriage in its forwardmovement.

In Fig. 3 the gathering instrument is seen as having been swung out tothe point where the charge is delivered into a glass-mold, (not shown,)and in this swing movement the wheel 25 on the swing-frame runs on thetrack 26, standing out from the carriage, and when it reaches thedepressed seat 74 the swing-frame and the gathering-iron arecaused todip slightlyto bring the glass into convenient proximity to the mold,(or to the marvering-block when said block is employed.) When thegathering-iron reaches the point of delivery, the carriage is stoppeduntil the charge is removed, and for the purpose of convenientlystopping the carriage automatically I may employ the following clutchmechanism, by which the motion of the chain 58 is controlled. A lever75is pivoted to the carriage,its handle standing rearward, so that ashoulder 76, Figs. 1, 2, and 6, on the lever will strike theclutch-shifting lever 65 when the carriage reaches the end of itsrearward travel and, moving it back,will disengage the clutch part 63,as in Fig. 3, wherein its levershoulder is engaged with the clutch-leverto hold the clutch open. To start the carriage forward, the hand-lever75 is raised by the attendant to release its shoulder from theclutch-lever, when the latter by its spring 64: again engages theclutch, the carriage moves forward, and the swing-frame is caused toswing into line as the carriage carries the gathering-tool into theworking chamber.

The hand-lever 75 is held in horizontal position by a pin d, Figs. 3 and6, on the railframe passing through a vertical slot in the lever, so asto hold its shoulder 76 in position to strike the clutch-shifting lever65 as the ICC carriage moves back. The forward movement of the carriageis also limited by opera- 7 tion of the controlling-clutch,and this isdone,

preferably, by means seen in Figs. 3, 12, 17, 19, wherein a rod 7 7,preferably between the rails at the working side of the machine,connectswith the clutch-lever and with an arm 78, pivoted to and rising from thefront trackrail, Fig. 12, so that the upper end of said arm stands inthe path of an arm 79, pivoted to and standing out normally horizontalfrom the side of the carriage. As the carriage moves forward its arm 79,standing horizontally, will be caused to strike against the vertical arm78 of the track-frame and, forcing said arm forward, will pull itsconnected rod 77, and with it the outer end of the clutchlever 65, and,disengaging the clutch, stops and holds the carriage still while thegather is being made. This is the position of these parts seen in Figs.3, 17, 16.

The backward movement of the carriage is effected upon the descent ofthe track-frame, preferably in the way which I will now'state. A stop80, preferably fixed at the front of the top cross-head of the basestructure,standing up, comes in contact with the arm 79, pivoted to andprojecting out from the carriage-frame, as the track-frame falls, and,lifting said arm, thereby releases it from the vertical arm 78, pivotedto the track-frame rail, as seen in Fig. 19 and by dotted lines in Fig.12. This allows the clutch-spring 64 to pull the rod 77 and itsconnected arm 78 back and allow the engaging of the clutch, rotate thechain-connecting shaft 37 to pull back the carriage and to swing out thegathering instrument. This stop 80 is made adjustable to give the exactlift to the arm 79, and for this purpose the stop is fastened to abracket.

As the outward sidewise swing movement of the gathering instrument andits swing-frame tends to lift the carriage in the direction of theswing, I prefer to provide it with a bearing-roll 81, Figs. 3, 12, and17, to resist the .tendency to tilt and to give steadiness to themovement of the carriage.

I have discovered that, difficulties in gathering glass from a moltenbody in a melting pot or tank, which I explain below, can be overcome byaccelerating the rotation of the gathering instrument as it leaves thesurface of the molten glass. Mechanism of various forms may be employedfor this purpose; but I prefer to use a belt-shifting device, which Ishall now describe.

The chuck-shaft 8 is driven by cone-pul- I leys, Figs. 10 and 13,mounted by a stud fixed to the chuck-frame above the chuck bearingblock9 and having a pinion 82 below the pulleys, which engages anintermediate gear 83, which in turn engages the pinion 84 on thevertical shaft 19, which has intermediate connection with thechuck-shaft. These conepulleys provide grooves for a driving beltcord 85and are for changing the speed of the gathering instrument, As thisinstrument is making the gathering it is rotated by the belt in thegroove in the lower largest pulley 86; but, referring to Figs. 9, 10,and 11, as the carriage settles down the roll 87 of the pivoted arm 88,standing out from the top of the swing-frame, comes in contact with theincline block 89 on a bracket rising from the .inner end of thebase-frame and lifting the roll end causes the other end of the pivotedarm 88 to be depressed, and thereby depressing its connected end of thepivoted arm 90 raises its roll end 91 against the under side .of thebelt and shifts it to the groove of the upper pulley .92. Thisaccelerates the speed of the gathering-iron and quickly winds off thethread of glass with which the gather terminates in the rising of theinstrument, and thereby prevents long threads of glass from being drawnout by the gathering instrument, which would seriously interfere withthe operation of the machine. The action of the lever-roll 91 to shiftthe belt-cord is supplemented by means of a pin 93, standing up from thepulley 96 just below the upper speeding-groove, so as to catch under thecord as it is being lifted and run' it into the upper groove. To moreparticularly explain this shifting of the belt-cord, I may state that asthe track-frame settles down with the carriage the roll end of the lever88 is brought upon the wedge-block 89, which causes the roll end of thelever 90 to rise and lift the belt, so that the pin 93, rotating withthe pulley, will catch under the belt, and thereby render certain itsshifting upon the upper small. pulley to double the speed of thegathering instrument. This increased speed is effected while thegathering end is rising from the molten glass with the gather and iscompleted as the roll 87 passes down 0d the incline block, which allowsthe roll end of the lever 90 to fall, and the pulley then having assumeda horizontal position and the instrument then raised from the glass thebelt will be again caught by the pin and run down into the groove of thelargest pulley, and thereby reduce the speed while the instrument isbeingmoved into position to deliver the glass, and thus to prevent itfrom being thrown oi the instrument, which might happen under a highspeed.

The block 89 for actuating the pivoted arm 88 is wedge-shaped at itsupper and lower ends to give it the function of a cam to operate thelevers 88 and 96, and the flat surface between the inclines is longenough to hold the belt-cord in the upper groove 92 a sulficient timefor keeping the speed on to wind 0% the wire-glass, and this wedge-blockis made adjustable on its supporting-bar to suit the movement of thetrack-frame. Usually a short period of this increased speed will sufficeto wind off the wire-glass and the time of such increased speed may becontrolled by The speed of the rotation of the gathering vating-clutch.

instrument in moving toward and from the {lower end of said leverengages the curved working chamber is the same in its gathering and inits delivering functions and is determined by the speed of the largestpulley, which is driven by the train of gear of which the gear 18 iscaused to make, say, three revolutions to one of the gear 17, whichconnects with the gear-train of the pulleys.

Referring to Fig. 2, it is when the hinged track-section assumes itshorizontal position that the pivoted arm 79, descending with thecarriage, comes in contact with and is lifted by the stop 80, and theclutch 63 is thereby released to again start the carriage back, as inFig. 19. Simultaneously with the tripping action of the arm 79 thecranks will be at their lowest point, and the rotation of the shaft 41should be stopped to prevent the lifting action of the cranks while thecarriage moves back. This may be effected by a clutch on the shaft 41.The part 94 of said clutch is toothed and is loose on the shaft, whilethe sliding clutch part 95 is also toothed and is splined on said shaftand is operated by a shifting-lever 96, which is pivoted at 97 to abracket 96' on the fixed lower cross-head 32 and engages theclutch-groove by the pin-lug, Figs. 7, 8, and 14. This clutch Icall theele- A spring 99 connects the shifting-lever 96 to pull the splinedclutch 05 into engagement with the loose section, while a tripping-arm100, pivoted to the forward end of the shifting-lever, extends forwardand terminates in a downward curved or inclined end 101 at the clutch.The clutch-shifting lever has a vertical swing movement on its pivot 97,while the arm 100, having the curved end 101, rests on a lug 102,projecting from the clutch-lever, as in Figs. 7 and 8, and has asidewise swing upon its pivot 103 and has two functions, one of which isa pushing function to push and swing back the hanging end of theclutch-lever and disengage the clutch, as in Figs. 7 and 14. Thispushing back of the clutch is effected by an arm 104, depending from thelifting cross-head in vertical line over the curved end 101 of thetripping-arm, so that on the descent of the lifting cross-head 30, thisarm 104 engages and presses upon the end 101 of the arm 100, and pushingit back pushes thereby the lower end of the hanginglever 96, which byits pin-and-groove connection, Fig. 8, with the sliding clutch 95'disengages the clutch and stops the rotation of the shaft 4]. and of thecrank-operating gear. The other function of this curved arm is fordisengaging it from the depending arm 104, by which the clutch 95 isheld disengaged to allow the clutch to be rengaged by the pulling actionof its spring. This tripping function of the curved arm is effected by alever 105, Figs. 2, 7, 8, and 14, which is pivoted to a bracket 100,depending from the fixed crossl1ead of the base structure, the saidlever extending above said cross-head, so as to stand at the off side ofthe trackframe, as in Figs. 3, 14, and 16, while the arm 100 aboutmediately of its length, so that when the upper end of this lever isforced to.- ward the track-frame its lower end will force the curved armaway from the clutch, and thus shove it sidewise off the end of thedepending arm 104, as shown by dotted lines in Fig. 8, to allow theclutch to be engaged. For this purpose the end of the arm 104 need onlyact on the narrow end 101, so that the side-tripping movement of the arm100 need only be slight.

The tripping action of the lever 105 is effected by the following means:The charge having been delivered from the gathering instrument, theattendant raises the handlever 65 to release the clutch part 63 andallow its engagement. The chain is thereby set in motion to move thecarriage forward. Having moved, say, about three inches, a projection107 from the off edge of the carriage, Fig. 3, near its front end comesagainst the inner end 108 of a bell-crank lever pivoted to a bracket onthe off rail 6 and forcing said inner end back toward the front causesits other arm 109, Figs. 3 and 16, to move inward against the upper endof the trip-lever 105, which is thereby forced inward to cause its lowerend to push the narrow end 10] of the arm 100 sidewise off the dependingarm 104, the position of the arm 100 when so pushed being indicated bythe dotted lines in Fig. 8. A spring 110 connects the bell-cranklever soas to return it to its normal position after it had been tripped by lug107. On the return of the carriage the projection 107 strikes and passesby the bellcrank. A spring 99, Figs. 7 and 8, likewise pulls the arm 100and lever-arm 105 back to their normal positions. A stop 111 holds thisbell-crank lever in its normal position against the action of the spring110.

I have stated that the gathering instru ment is rotated continuously topick up a quota of glass and to hold it thereon while it is being movedout of and away from the working tank to the place of delivery, and,referring to Figs. 1 and 2, it will be seen that the pulleys by whichrotation is efiected must by the dipping of the gathering instrumentchange their position with respect to the driving connections, which arefixed at the rear end of the track-frame. As the hinged section of thetrack-frame dips, the carriage thereon dips also, and the frame 13 ofthe pulleys is swung forward and downward to the extent of theinclination of such dipping. This forward swing of the pulleys pulls thebelt-cord forward on its supporting-roll 112, while the upward swing ofthe hinged tracksection to a horizontal plane will relax the belt-cord.To provide for this and maintain the tautness of the belt-cord in thechanging positions of its pulleys, I arrange a suitable slack-adjuster,which may consist of a system of pulleys on the rear end of thetrack-frame, as in Figs. 1 and 18, so as to provide aweighted slack inthe belt-cord to keep it always under proper tension. Referring to thesefigures,t-he line-shaft 37 has a pulley 113 on its rear end, and thebelt 65 from one side ofthe speedingpulleys passes thence over a pulley114 at the top of a frame 115, thence'down under said shaft-pulley 113,up over a pulley 117 on the other side of the frame, thence down under apulley 118 below the frame, thence over a top pulley 119, thence downunder a bottom pulley 120, thence over a top pulley 121 to the otherside of the speeding-pulleys. The two bottom pulleys are connected by aweighted tie 122 and are free to rise and fall with the pull and slackof the belt, and thus keep it taut. The fixed and the liftingcross-heads are made adjustable by bolts engaging the fixed and thehollow standards, so as to give exact movements to the lifting-crankconnections.

The operation of the machine constructed as above described is asfollows: When the carriage 5 is at the end of its rearward travel, itscontrolling-clutch is disengaged and the gathering instrument stands-outat the side of the machine at the place at which it is desired todeliver the charge, Fig. 3. Starting from this point, the operatorcauses the carriage to travel forward by raising the handlever 75,thu'soperating the clutch 63 and cansing the chain. 58 to move and to advancethe carriage. The liftingdevices are then set into operation as aboveexplained, and the trackframe is caused to rise slowly, lifting with itthe carriage and gathering instrument, and either before orsimultaneously with the lifting of the track-frame the swing-frame byoperation of the guide-arm 71 is swung back into line with the workingchamber of the melting-furnace. The advance of the carriage introducesthe gathering instrument into the furnace, and the carriage preferablyreaches the end of its travel and is stopped by automatic disengagementof the clutch 63 before the track-frame has been completely raised. Asthe track-section 28 rises its forward hinged section 27, beingsupported upon the fulcrum-bar or supporting-guide 66, will incline ortip to an extent and with a speed depending upon the curvature of thebar 66 and upon the adjustment of the screw 70, and as the track-framenears the end of its ascent it will cause the rotating gathering-tool toincline and dip into the molten glass at a high pitch. The track-framethen begins to descend, and by the action of the supportingguide 66,explained below, the hinged section of the track-frame is brought towarda horizontal position, thus simultaneously raising the end of theinstrument and giving it a forward motion in the glass, which materiallyenhances the operation of gathering. When the gathering instrumentleaves the glass, its speed of rotation is accelerated, as aboveexplained, for a period of time sufficient to permit the winding off ofthe threads of glass which hang from the gather.- As the trackguide-armengages the rollers 72, and the V swing-frame is thereby swung on itspivot 22 so as to bring the gather of glass to the place of deliveryeither at the mold or marveringblock. As it reaches the end of itsmotion the swing-frame and gathering instrument dip, and the carriagebeing then at the end of its backward travel stops and the swingmovement of the gathering instrument ceases. This completes the cycle ofoperation, which is repeated as often as desired. The gatheringinstrument may be rotated continuously by the pulleys 86 or 92 duringthe movements of the machine, though it is only necessary to rotate itwhile it carries the gathering of.

glass.

Referring to Figs. 1,2, 21, I will now more particularly describe thepath of the gather-' ing instrument as it is controlled and guided bythe supporting guide or fulcrum-bar 66. The fulcrum-bar is curved, andin the position seen in Fig. 1 the wheel 69 is at the highest part ofthe curve when the gathering instrument is at its highest pitch, withits gathering end on the surface of the glass. Then the liftingmechanism having reached its highest point begins to descend. Thefulcrum of the hinged track part will roll down on the fulcrum-bar, andthis will cause the gathering-point to move forward in the glass, whileat the same time the driven end of the iron and the rolling fulcrumsettle down, causing the gathering-point to gradually rise, describingan advancing curve struck from the hinge of the track-frame. Accordingto the pitch of the gathering-iron will be the extent of its advancegathering movement on the surface of the glasssay from two to two andonehalf inches, more or less. In this gathering action the driven end ofthe iron will descend twice as fast as the gathering end rises.Illustrating this in Fig. 21, let 124 be the highest point of the pitchof the gathering-iron, 125 the movable fulcrum-point, and 126 the lowestor gathering point. Then the lowering of the iron from its highest pointwill in proportion cause it to lower at its movable fulcrum,

and thereby cause the gathering end to advance from 126 to 127, slowlyrising in describing the are 128. In describing this are the gather ismade and the wire-glass wound off, the rise of the gathering end beingpreferably about six inches and the descent of the driven end 124 abouttwelve inches. This would bring the gathering instrument and itscarriage on a level with the rack-frame,

as in Fig. 2, with the rolling fulcrum at the lowest end of the concavefulcrum-bar. In

ICO

this gathering action the rolling fulcrum and the track-liftingmechanism start from their highest point and settle down in unison, sothat the lifting mechanism controls the descent of the track-framesimultaneously with the action of the rolling fulcrum in giving thegathering action to the iron and in bringing it to a level. In thisgathering action the iron rotates and is thereby subjected to a pullingaction in winding the sticky glass upon it as it rises, and this tendsto pull the iron to one side, and therefore would, unless prevented,turn the swing-plate in the same direction. To prevent this, I providethe rear rail with a bracket-fender 123, Fig. 20, against which theguide-arm 71 is caused to bear, and thereby resist the turning of theswing-plate from this cause.
